public static void main(String[] args) throws Exception {

//创建一个空的Document对象

Document doc = DocumentHelper.createDocument();

//创建一个根元素

Element stus = doc.addElement("students");

//创建子元素

Element name = stus.addElement("name");

//为子元素赋值

name.setText("张三");

Element sex = stus.addElement("sex");

sex.setText("男");

Element age = stus.addElement("age");

age.setText("20");

Element phone = stus.addElement("phone");

phone.setText("1222334455");

//创建输出语句对象,将对应的文档内容格式化

OutputFormat of = OutputFormat.createPrettyPrint();

//将创建的xml文件写入到文档中

XMLWriter writer = new XMLWriter(new FileWriter("/students.xml"),of);

//写入

writer.write(doc);

//刷新

writer.flush();

//关闭流

writer.close();
